That light came on because the on board computer system See's a PROBLEM with the emissions system. You will need to have the engine scaned with an engine scanner to see what the problem is. Then you will have to repair whatever is wrong and then clear the codes with a scanner and the the light will go off. If you don't repair the system and turn the light off then it will just come back on.
You need an OBD II scanner.....about $40 - $150 depending on where and which features you want.
no it doesnt
How do I reset the service engine light on a 2003 Chevy Trailblazer?
battery dicunnect for 3 min. or take to auto parts store and have cleared
That REQUIRES an ENGINE SCANNER to do that.
Yes but, if the light is flashing no.
The vehicle is due a service soon
Normally a flashing check engine light means you have a misfire. Do not ignore this as an engine misfire will damage the O2 sensor and the catalytic converter which are very expensive to replace. Have this repaired immediately.
You must first find out what caused it to come on and that will REQUIRE an engine scanner. After you have scanned the engine and read the engine codes and then repaired the problem. You will be able to turn the light off with the scanner.
That requires an OBDII engine scanner.
the service engine light is on due to the fact that there is a problem with your truck, this is confirmed by the way your truck is running. you need to get a engine diagnostic check at an auto shop. may just need a tune-up, or the truck has a bad sensor, or engine woes.
Maybe you should service the engine soon. :P
